Access Context from current thread

Hi all,

Is there anyway to access the transaction manager Context from the  
currently running thread? The reason I am asking is hibernate has a  
plug-able CurrentSessionContext. If the Context could be plucked from  
the thread then you could grab a hibernate Session out of the context  
to enable long running transactions. I can see this being useful in  
ways other than with just hibernate.
